WebbThe electron starts from rest (near enough) so the kinetic energy gained is given by ½ mv 2 where m is its mass and v is its speed. So we can say that: ½ mv 2 = eV The mass of the electron is m = 9 × 10-31 kg The electronic charge is e = 1.6 × 10-19 C Webbp = m v. You can see from the equation that momentum is directly proportional to the object’s mass ( m) and velocity ( v ). Therefore, the greater an object’s mass or the greater its velocity, the greater its momentum. A large, fast-moving object has greater momentum than a smaller, slower object.
